SPRING LOCK.

Application Vtiled March 2B, 1925.. SeralrNo. 18,937.

This invention relates to spring locks and more Aparticularly tor ysuch locks as are desired to occupy a minm'ium amount ot space. lt is accordingly an objectv ot this invention to provide` an efficient spring lock. It 1s also an robJect of this invention to provide such a lock which is compact,

which is easilyoperated, and which may ben economically constructed.y

71th the above-and other objects 1n View,

as willvbe apparent, this invention consistsL in the combination, construction `and arrangement of parts, all as hereinafter more fully described, claimed and illustratedl in the accompanying drawings.H

On the drawings: Figure 1 represents `an elevational view withparts removed of a lock embodying this invention.

Figure 2 is a cross-sectional view of the lock of Figure 1.

Figure 3 isan elevational viewwith parts removed showing thelock of `Figure 1 in unlocked position.

Figure 4 is .a detailsectionalview along the line 4-4 of Figure2.

As shown on the drawings: Y As shown in Figure 2, numerals 1 and 2 represent two parts whichr are desired to be locked together. Rigidly secured to the part 1 is a latch member The member 3 has its lowerv portion planed to fit within a pair of plates 4 and 5 (Figure 2). The plates 4 and 5 are rigidly se'zured to the part 2 in 'spaced position. The part 2 is recessed to receive therein a lock 6. The lock 6 comprises a cylinder 7, a barrel S eX tending into said cylinder and therethrough and an apertured plate 9. The barrel 8 is slotted at 10 to receive* a key 11. The key 11 has a double edge which coacts with tumblers 12 on either side of the slotKlO for thekey 11, the barrelr 8 and cylinder 7 being suitably apertured for this purpose. Outside of the tumblers 12 are tumblers- 13, the tumblers 13 being alined with the tumblers 12. The cylinder 7 is cut to a smaller diameter adjacent the tumblers 12 and 13, as shown in Figure 4, to receive a spring 14 which is adapted topress the tumblers inwardly. The lengths of the tumblers 12 and 13 bear the same relation with the edges of the key 11 as in an ordinary Yale lock. with the exception that. in this case a double edge on the key and a double set ot tumblers therefor is provided so as to obtain a vmaximum number oi locking members with a minimum length of lock. rfhe barrel S extends through the inner plate 4 andhas provided on the'inner end thereof a member 15; A member 16 is supported around the end of the barrel 8 and has integral therewith a pair of arms 17. The

member 16 is normally spring pressed in upward Vposition by means of springs 18.

As shown inFigure 1, the barrel 8 is in locked Yposition with the member 15 thereron inposition as shown in said figure. In

gs 18 have ypressed this position the sprin the member 16' in upward position so that. the arms 17 on the latter engage a pair of kcam members 19 inwardly for engaging a Vpair `of springs 2O secured to a pair. or locking members 21. The locking members 21 being pressed inwardly vengage with the latch member 3 for locking the parts 1 and 0- The lockingy members 21 are pivotally supported upon pins 22Ymountedbetween the plates 4 and 5. The members 19 are shaped so that when the barrelv 8 is turned to unlocked position andthe member 1.55 thereon engages the member 1G for drawing the latter downwardly to the position shown in Figure 3, the arms 17 will cam the lower portions ot themembers 19 inwardly. The members19 are so supported on the locking members 21 below the pivot points 22 thereof that said members 19 lare cammed inwardly by the arms 17 on the downward movement of the latter that the upper ends of the locking members 21 will be forced outwardly disengaging the latch 3. It will be `seen that l have provided a very com.- pact, simple, rugged and economical lock.

I am aware that many changes may be made,'and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise thannecessitated by the prior art.

I claim as my invention: Y

1. A lock ot the class described compris Ving Aa latch member, pivotal locking means connected to said reciprocable member tor actmning` the same.

2. The combination in a lock ot the class described, et a latch member, lockinig` means for engaging' said latch member when in lockingv position, a reeiprocable member for actuating said locking` means to and from locking,Y position, a resilient connection between said reciprocable member and said locking means, and a rotatable `member tor actuating said reciprocable member.

ylhe combination in a lock et the class described, ot a latch member, 'locking means engagingsaid latch member, a reciprocable member tor actuatinl the locking means to locked position, a resilient connection between said reciprocable member and said` locking means, a rotatable member adapted to actuate said reeiprocable meml er, and means ior normally holding said reciprocable member in actuated position :tor lieeping said locking means in locked position.

rllhe combination ot a pair ot parts to be locked, a latch member rigidly secured to one of said parts, a pair ot spaced plate members rigidly secured to the other ot' said parts, said latch member being` adapted to extend into said plates when the parts are together, pivoted lool-:ing` means mounted between said plates, a reciprocable member between said plates, a resilient connection between said reciprocable member and said locking means, means associated with said reciprocable member when in one position tor actuating,` said locking` means to lock said latch member therewith, means associated fith said reciprocable member when in an other position tor actuatine said loclrin means to disengage said latch member, means tor normally holdingl said rcciprocable member in the lirst position, and a ro` tatable member for actuating said reciprocable member to the second position.

5. The combination with a pair et parts to be locked, a latch member rigidly secured to one ot' said .parts and extending outwardly therefrom toward the other ol said parts, the other ot said parts being` adapted to receive the same, pivoted locking,` means on the last mentioned part, a reciprocable member on the latter part, a resilient connection between said reciprocable member and said lockingmeans, means associated with said reciprocable member when in one position tor actuating said locking means to lock said latch member therewith, means associated with said reciprocable member when in another `position for actua'iting' said locking; means to discngage said latch member, land a rotatable member tor actuating said reeiprocable member.

G. A lock ot' 'the vclass described compriing,` a latch member, pivotal locking means adapted to engage with said latch member, spring means operatively connected with said locaing means, Vcam means operatively connected with said spriiml means, a recipro cable member slidably connected with said cam means for actuating said first means and means operatively connected with said reciprocable member tor actuating the same.

7. A lock of the class described comprising` a latch member, pivotal locking means adapted to engage said latch member tor locking` the same thereto, and a rotatabhl member resiliently and operatn'ely connected to said locking means tor actuating` the same to and trom locking position.

In testimony whereof l have hereunto subscribed my name.
